Its role in the system

The market for loans packaged as securities: governments, banks and companies issue bonds, and investors buy them for the fixed income (the coupon) and the repayment of the principal on time. This is the largest capital market; it is here that the yield curve — the “price of time” — is formed, the curve from which mortgage and loan rates are calculated and against which almost any asset is valued.

Functions

  1. Financing the state — governments cover budget deficits and refinance old debt with bonds (🇺🇸 Treasuries, 🇩🇪 Bunds, 🇬🇧 gilts).
  2. Financing companies and banks — corporate bonds provide long money directly from investors, bypassing bank credit; riskier issuers issue high-yield bonds (rated below investment grade) with a higher coupon.
  3. The money market — borrowing for terms from one day to a year: treasury bills, commercial paper, repo (a loan against bonds with an agreement to buy them back). This is where banks and funds manage liquidity every day, and where the central bank passes its rate into the economy.
  4. Securitisation — thousands of similar loans (mortgages, car loans, loans to companies) are pooled and sold to investors as securities — MBS (mortgage-backed), CLOs (on corporate loans) — in tranches of different risk.
  5. The benchmark for risk — the yield on government bonds is treated as the base “risk-free” rate; the premium over it (the spread) shows how much the market trusts a particular company or country.
  6. Targeted issues — bonds tied to specific projects or indicators: green, social, transition. 🇪🇺 A voluntary European Green Bond standard has applied since December 2024: the name may be used only if all proceeds go to activities in the European taxonomy (with up to fifteen per cent left flexible), and the external reviewer is registered with ESMA; more than twenty-two billion euro was issued under it in the first year. 🇨🇳 In China the same shift runs mainly through green lending rather than bonds: the stock of green loans exceeds six trillion dollars, and the main channel is the bank, not the market.

What makes it special

  • Price and rate sit on opposite ends of a see-saw: when rates rise, the prices of bonds already issued fall — the more so the longer the term (duration). That is what burned British pension funds in 2022 and Silicon Valley Bank in 2023.
  • Mostly an over-the-counter market: most bonds trade not on an exchange but through dealers — banks that hold an inventory of paper and quote prices. For government bonds there are primary dealers who commit to bidding at auctions.
  • Ratings decide who is allowed to buy: the ratings of S&P, Moody's and Fitch split the market into investment grade and high-yield; many pension funds and insurers may hold only the former, so a downgrade forces sales.
  • The central bank is the most influential participant: through repo and bond purchases (quantitative easing, QE) it directly affects yields; banks hold government bonds as a liquidity buffer. Green bonds have been legally possible since 2021, but as of 2026 not a single issue has taken place: the machinery for verifying that a project is genuinely green, and the institutions around it, are still missing.
  • 🇨🇳 China: the world's second bond market, with almost no foreigners in it: the onshore bond market is second only to the United States (more than twenty-five trillion dollars), yet foreign investors hold less than three percent of it; trading happens mostly on the interbank market and access from outside runs through the Bond Connect scheme from Hong Kong. Its peculiarity is the local government financing vehicles (LGFVs): cities built roads and bridges through separate companies so that the debt would not show in their own budgets. Since November 2024 the state has been swapping that hidden debt into ordinary regional bonds — a programme of twelve trillion yuan.
  • 🇯🇵 Japan: an enormous debt, owned by its own people: government debt exceeds two hundred percent of GDP, the highest among developed countries, but it is in the country's own currency and in the hands of its own investors. The Bank of Japan held yields down for years by buying bonds outright (yield curve control was scrapped in March 2024) and as of March 2026 owned roughly half of the entire government debt — some five hundred and thirty trillion yen out of one thousand one hundred and fifty. Which is why it is leaving the market so slowly: any abrupt selling would push yields up and make the budget more expensive.

Why it matters

When the debt market breaks, the state cannot fund its budget, companies cannot refinance their debts, and banks and funds suddenly lose liquidity: the collateral everyone thought was safe gets cheaper, and margin calls set off a chain of forced sales.

🇺🇸 Orange County, December 1994

For years the treasurer of the Californian county made money betting that rates would not rise: he borrowed against bonds and bought complex interest-rate paper. When the Federal Reserve began raising rates in 1994 the loss reached around 1.6 billion dollars, and the county declared what was then the largest municipal bankruptcy in the United States. The case shows how bond prices fall when rates rise — and how leverage turns that into a catastrophe.

🇺🇸 The “taper tantrum”, May–September 2013

Federal Reserve chairman Ben Bernanke merely hinted that the central bank might start reducing its bond purchases. The yield on ten-year US bonds rose within a few months from just under 2 per cent in May to almost 3 per cent by September, and capital began flowing out of emerging markets. The case shows how sensitive the debt market is even to the words of a central bank.

🇮🇹 BTP Valore: Italy borrows from its own households, 2023–2024

In 2023 the Italian treasury launched BTP Valore, a bond sold only to private savers. The first issue in June 2023 raised about 18.2 billion euros through 654,575 orders, and the February 2024 issue set a record of about 18.3 billion euros and 656,369 orders. Over these years households' direct share of Italian public debt roughly doubled. The case shows how the debt market mobilises a country's own savings and shifts the state's debt into domestic hands.

  • Sovereign Wealth FundsSovereign Wealth Funds are patient buyers in the Debt market: they come for the long term and can buy precisely when other investors are selling.
  • State Insurance & GuaranteesThe bond market buys paper that the state stands behind: notes under export agency cover, government-guaranteed issues and catastrophe bonds from state insurance pools — the price of such debt depends on the guarantor, not the borrower.
  • Stock marketThe Debt market and the Stock market are the two halves of a company's capital: debt is cheaper and tax-deductible but has to be serviced on schedule, equity is dearer but carries no compulsory payments.

Regulation and supervision

Supervised by: Financial Market Infrastructure

Bonds mostly trade over the counter rather than on an exchange, so supervision fights for transparency: issuers register a prospectus and disclose reports, dealers report trades (🇪🇺 MiFIR and the coming consolidated tape, 🇺🇸 the TRACE system), and 🇪🇺 CSDR disciplines settlement.

Standards: IOSCO Objectives and Principles of Securities Regulation · EU Prospectus Regulation 2017/1129 · EU MiFIR 600/2014 (post-trade transparency, consolidated tape) · EU CSDR 909/2014 · US Securities Act 1933; FINRA TRACE rules; MSRB rules for municipals
